Mexican president signs education reform - Article Photos 3/3

Mexico's President Enrique Pena Nieto exits the stage after delivering a speech at the National Palace where he signed into law on new education reform, in Mexico City, Monday, Feb. 25, 2013. The law which was approved by Congress in December, calls for creation of a professional system for hiring, evaluating and promoting teachers without the "discretionary criteria" currently used in a system where teaching positions are often bought or inherited.
